Gateway National Recreation Area exists within one of the most urbanized areas of the country, yet the park includes grasslands, woodlands, sand dunes, beaches, ponds, salt marshes and forests. Each of these ecosystems is a home to a surprising variety of animals, plants, amphibians, insects and other creatures. One way to learn about the diversity of life at Gateway is to get to know each of the ecosystems.
Urbanization has a profound effect on Gateway's ecosystems, including stormwater runoff into Jamaica Bay. The U.S. Geological Survey has produced two video podcasts on similar issues: how stream ecosystems react to stormwater and impervious surfaces.
